排便习惯改变——腹泻大便变细

Change in bowel habit: Diarrhea and Narrow Stools

患者因排便习惯改变1个半月入院。乙状结肠肿物阻塞肠腔,肠镜无法通过,但CT、钡灌肠提示存在另一高位肿瘤。术中探查全大肠,证实同时存在脾曲癌灶。术后两处病变病理为恶性,诊断为同时性双原发癌。多原发性大肠癌易漏误诊,应术前多种检查手段相结合,术中全面探查,术后随访,行标准化治疗。

The patient arrived at our hospital with a complaint of diarrhea and narrow stools. His colonoscopy couldn＇t pass through the sigmoid because of the obstruction of tumor, but CT and barium enema indicated another upper tumor. Checking the colon and rectum during operation confirmed the tumor of splenic flexure. The pathological diagnosis of 2 tumors was malignant. Final diagnosis was Synchronous Carcinoma （SC）. Missed diagnosis or misdiagnosis of multiple primary colorectal carcinoma is not rare, the combination of enough pre-operative examination, overall operative exploration and post-operative follow-up is necessary. The standardized curative therapy is also important.
